Shady or overreacting ?

How would you guys react if your SO disinvites you from going to their house that night & doesn’t explain why & when you ask they say “don’t worry about it sweetheart” and then lag for like 1-2 hours at around 12am (when they usually talk/call you) & pretend that they didn’t see your text even though you know they go on their phone a lot.... is that shady to any of you or am I overreacting bc I am getting heated.... even tho he never disinvites and that night he “forgets” to respond...?

Update: got in a fight & started blaming me bc he thinks someone else has my attention bc I responded to his 2 hour text 5 minutes late.... 🧐
